The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.
Dec 24 2013 · A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m although much smaller sizes are used pharmaceutically.
WARNING✕The ball mill has a great similarity in appearance with rod mill which is most widely used in the cement and fertilizer production. Different from rod mill ball mill is also used as dry type grinding mill which is the main difference of the ball mill and rod mill because of its different grinding media.
Ball Mills vs Rod MillsAM King Ball Mills vs Rod Mills. Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some Get Price. The Difference Between the Ball Mill and Rod MillEssay

From the volume the ball mill divide into industrial ball mill and laboratory use the small ball mill sample grinding test. In addition these mills also play an important role in cold welding alloy production and thermal power plant power production. SAG mill vs Ball mill Crushing ratio
Jun 11 2019 · In the order you have listed a ball mill can fine grind down to <400 mesh if needed a rod mill will efficiently grind to 150/200 mesh range and a roll mill can do a /- 100 mesh. The ball and rod mills are similar in appearence as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium.
From the volume the ball mill divide into industrial ball mill and laboratory use the small ball mill sample grinding test. In addition these mills also play an important role in cold welding alloy production and thermal power plant power production. SAG mill vs Ball mill Crushing ratio
Bond Work Index Tests. Grinding Solutions offers a range of Bond Work Index Testing from crushability and abrasion to ball and rod mills. For more information on the tests please see below Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi) also known as the Impact Work Index.
Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency better grinding performance and lower energy costs.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill usually a high-carbon steel can vary in both the length and the diameter. However the smaller the rods the larger is the total surface area and hence the greater the grinding efficiency.
1. Short Cylinder Ball Mill The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter i.e. the ball mill with L ≤ 2D is short cylinder ball mill which is usually of single bin structure mainly used for rough grinding or primary grinding operation and can realize the wide use of 2-3 ball mills in series. 2.
Apr 09 2015 · Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter so the kinetic energy of a single dropping ball is smaller than a rod.
Oct 12 2017 · Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
Nov 23 2019 · Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material s hardness Ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc. Rod mill is suitable for grinding brittle material such as rare metals.
Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30 of the power used in a ball mill. When they are worn rods must not stretch but break in rather small pieces so that they can exit
Dec 23 2013 · Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls it is similar to ball mill
